PAINT A'ND VARNISH REMovER.

No Drawing.

This invention relates to improvements in compositions of matter and has more particular reference to a compositionfor the removal of paint and varnish from wood or metallic surfaces.

The primary object of the compositionis to provide a varnish and paint compound especially adaptable to removing paint and varnish from motor vehicles. The compound, however, is equally eflicacious in the removal of paint and varnish from furniture or other objects. The compound or composition of matter 'may be manufactured at a'nominal cost and is presented to the trade in powdered form and by the addition of water is ready for instant use and application.

With the above objects in view, the invention consists of the mixture together of sodium hydroxide, hydrated calcium, .fullers portions toproduce one hundred pounds of the compound in powdered form:

Sodium hydroxide 35 lbs. Hydrated calcium 40 lbs. Fullers earth 5 lbs. Tri-sodium phosphate 5 lbs. Red manganese oxide 10 lbs. Powdered starch 5 lbs. Methyl-salicylate 1 dram.

The above ingredients are thoroughly The sodium'hydroxide has an immediate Application filed December 6,1926. Serial No. 153,045.

The fluid or composition may now be applied to the material or surface from which the paint or varnish is to be removed. For this purpose preferably a fibre brush is employed and the composition or fluid is permitted to remain on the surface from fifteen to twenty minutes, or as long as may be required to soften all of the paint or varnish. When the paint or varnish is sufficiently soft, the composition is then flushed off with a stream of water.

softening efl'ect on the paint or varnish and the hydrated calcium, combined with the full'ers earth has a neutralizing effect on the acids and prevents any reaction on the metal. The tri-sodium phosphate acts to start the solutionworking quickly, while the red manganese oxide acts as a neutralizer to prevent injury to the operators hands or body. The various ingredients are held together in the compound as an adhesive mass by the addition of the starch, and also to cause the com- 1 position to adhere sufliciently to-the surface to whichapplied. In order to offset and neutralize any offensive odor emanating from the compound, the methyl-salicylate is added.

The composition will remove paint and var nish from metal-or wood, and if the surface is thoroughly washed afterwards it will not be necessary to use any other ingredient, such as gasoline or vinegar,'to prevent the paint from slipping.

What is claimed is: v

A dry powder paintand-varnish remover formed by mixing together sodium hydroxide 35 lbs, hydrated calcium 40 lbs., fullers earth 5 lbs., tri-sodium phosphate 5 lbs., red manganese oxide 10 lbs., powdered starch 5 lbs., and methyl-salicylate 1 dram.

In testimony whereof we aflix our sigma-J 5 tures.
